Total hip and knee arthroplasty (THA and TKA respectively) are reliable and successful interventions in terms of relieving pain and improving joint function. Paucity exists on long- term data concerning patient satisfaction and patient related outcome measures (PROMs) after THA or TKA. We aimed to evaluate the long-term patient satisfaction and PROMs at least ten years after THA and TKA.
A cohort of THA and TKA patients from a randomized clinical trial was used. At least ten years after primary arthroplasty, patient satisfaction was evaluated by means of three questions: would you still consider surgery knowing now what a THA/TKA surgery consisted of? Would you recommend the surgery to friend or relatives? How satisfied are you at this moment with the THA/TKA. Oxford Hip/Knee score, EQ5D score and RAND36 scores were recorded.
A total of 123 patients were available for analysis. Respectively 78% and 64% of the THA/TKA patients would reconsider to undergo the same surgery again, 94% and 76% of them recommended the surgery to a friend or relative and mean score of satisfaction was 83.1 and 80.8 of the THA/TKA patients. The scores indicated that both THA and TKA patients are very satisfied at more than 10 years of follow-up. Comparable function and quality of life scores at a minimum 10-year follow-up after initial surgery were found in both groups.
In conclusion, we demonstrated that at a minimum of 10-year follow-up both THA and TKA patients are very satisfied, although THA patients being more satisfied compared to TKA patients.
